Bovine Tyrosinase (TYR) ELISA Kit
Due to the possibility of mismatching between antigens from other origin and antibodies used in our kits (e.g., antibody targets conformational epitope rather than linear epitope), some native or recombinant proteins from other manufacturers may not be recognized by our products.
Principle of the Assay
The microtiter plate provided in this kit has been pre-coated with an antibody specific to TYR. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to TYR. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After the TMB substrate solution is added, only those wells that contain TYR, biotin-conjugated antibody, and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution, and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of TYR in the samples is then determined by comparing the O.D. of the samples to the standard curve.
For Use with serum, plasma, and cell culture supernatants. For Research Use Only. Not for use in diagnostic procedures.
Target Information
This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds (By similarity). Catalyzes the initial and rate limiting step in the cascade of reactions leading to melanin production from tyrosine (By similarity). In addition to hydroxylating tyrosine to DOPA (3,4-dihydroxyphenylalanine), also catalyzes the oxidation of DOPA to DOPA-quinone, and possibly the oxidation of DHI (5,6-dihydroxyindole) to indole-5,6 quinone (By similarity).

Performance Characteristics
| REPEATABILITY |
Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level TYR were tested 20 times on one plate, respectively. |
| SENSITIVITY | The minimum detectable dose was 25ng/mL. |
| ASSAY RANGE | 78.1-5000ng/mL |
| SPECIFICITY | This assay has high sensitivity and excellent specificity for the detection of TYR. No significant cross-reactivity or interference between TYR and analogs was observed. Note: Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between TYR and all analogs, therefore, cross reactivity may still exist. |
